Abstract: PURPOSE: To provide the system which monitors the source address of an incoming packet on a repeater and compares it with an internally stored value. CONSTITUTION: This is a system used for a network and a system which authenticates a data packet, gives safety for securely preventing unauthenticated data from being received, performs improved monitoring of data packets sent and received through the network, and detects changes of the network topology. The repeater used for this system provides improved features by giving detecting and interpreting capability for packet data, and a source address(AS), a destination address(DA), and a field.
